摘　　要：针对汽车轮胎气压工况的特点,设计汽车胎压监测系统(TPMS).采用嵌入式实时操作系统μC/OS-Ⅱ为软件平台,以多任务的形式进行程序设计,并采用性能优越的32位ARM嵌入式处理器作为硬件处理平台.试验结果表明,该系统可有效防止轮胎在非正常气压下长时间行驶而发生事故,提高了汽车的主动安全性.系统的设计为胎压监测提供了一个有效和可靠的解决方案.Tire pressure monitor system（TPMS） of vehicles with high reliability and having good real-time is designed, considering the characteristics of vehicle tire pressure. Embedded real-time operating system/aC/OS-Ⅱ is adopted as the software platform, with software designed in multitask, and 32 bit embedded ARM processor is used. Accident can be prevented effectively when a tire from running out of normal pressure for long hours, and automobile active safety is increased. This tire pressure monitoring system provides an advantageous and reliable solution for tire pressure monitoring system.
